Emergence of the stellar halo of NGC 1042 as the depth of images increases. The panel shows the galaxy NGC 1042 at three different surface brightness limiting depths (3σ; 10″ × 10″): SDSS 26.9 mag arcsec⁻² (r-band), Dragonfly 28.0 mag arcsec⁻² (r-band) and LBT 30.5 mag arcsec⁻² (r-band). In the case of SDSS, we show the visual aspect of the galaxy in two different ways: (a) when the original SDSS pixel scale is used (i.e. 0.396″) and (b) when the SDSS data is rebinned to the pixel size of Dragonfly in these images (i.e. 2″). A non-symmetric stellar halo (with surface brightness μ_g > 29 mag arcsec⁻²) is observed in the LBT image. In all the stamps, the background in white and black is built by summing g and r filters to enhance the detection of low surface brightness features. North is up and east to the left.
